I have looked into this more deeply, and the patch that you are proposing
is for Freetype pre1.4, not for Freetype 2 at all.
What appears you are wanting, are the freetype "demos" programs. Those
do not ship currently with Red Hat Linux, however I have planned on adding
the demos, and have included them in the src.rpm even though they do not
currently build in it. I will add a new subpackage "freetype-demos" which
contains these executables in the freetype 2.0.4 release.
